However, I have been awarded New Super Mario Bros. Wii early because of my excellent scores in school, and I find it to be harder than the original on the Nintendo DS. I have been spending Sunday and Monday playing it. It's fine, although I've expected better. (Like an better variety of characters, and world themes, which are the same as the DS version.)
But I'm not going to review it this second, I should at least complete the game first, or get 95% completion. =P
UPDATE: Here is an new image I just completed. Enjoy.
